Reliance On Unverifiable Observations Hinders Successful Conservation Of Wildlife Species

June 25, 2008

This is interesting… and it ties in with a great talk I heard once about Thylacine sightings in Tasmania .. of which there are many. 

Reliance On Unverifiable Observations Hinders Successful Conservation Of Wildlife Species (June 24, 2008) — Researchers from the US Forest Service’s Pacific Northwest and Rocky Mountain Research Stations examined three cases of biological misunderstandings in which unverifiable, anecdotal observations were accepted as empirical evidence. Ultimately, they found that this acceptance adversely affected conservation goals for the fisher in the Pacific states, the wolverine in California, and the ivory-billed woodpecker in the southeast by vastly overestimating their range and abundance. The researchers’ findings appear in the current issue of the journal BioScience. … > full story

Another growing threat is loss of habitat, due in part to impacts from global climate change. … > full story

These pictures are not the greatest, but I’m hoping someone can tell me if they are D. delphis or D. capensis. I am leaning towards D. delphis, but the more I look at them and read up on it, the more unsure I am.

Iberian Lynx Watching

June 3, 2008

I’ve just uploaded a short note from Richard Webb to my website about a visit last month to Sierra de Andujar near Granada (Spain), which seems to be the place to see Iberian Lynxes these days.  Richard succeeded and I am heading that way myself in a few weeks.
